Also known as GLUT7

Summary

SLC2A7 (solute carrier family 2 member 7, HGNC:13445) is a protein-coding gene on chromosome 1p36.23, encoding Solute carrier family 2, facilitated glucose transporter member 7 (Q6PXP3). Probable sugar transporter.

SLC2A7 belongs to a family of transporters that catalyze the uptake of sugars through facilitated diffusion (Li et al., 2004). This family of transporters shows conservation of 12 transmembrane helices as well as functionally significant amino acid residues (Joost and Thorens, 2001 [PubMed 11780753]).

Literature-anchored findings (GeneRIF, showing 2)

  • Unusual substrate specificity and close sequence identity with GLUT5. GLUT7 may represent intermediate between class II GLUTs and class I member GLUT2. Comparison may give key to structural determinants for recognition of fructose as a substrate. (PMID:15033637)
  • a hydrophobic residue is a key determinant of fructose transport in SLC2A7 (PMID:16186102)

UniProt curated annotations — full annotation on UniProt →

Function. Probable sugar transporter. Even if its physiological substrate is subject to discussion, it is able to transport glucose and fructose. Does not transport galactose, 2-deoxy-d-glucose and xylose.

Subcellular location. Cell membrane. Apical cell membrane.

Tissue specificity. Expressed in small intestine and colon. Weakly expressed in testis and prostate.

Activity regulation. Glucose and fructose transport are inhibited by the flavonoid apigenin.

Induction. Expression is increased in presence of fructose.

Similarity. Belongs to the major facilitator superfamily. Sugar transporter (TC 2.A.1.1) family. Glucose transporter subfamily.
